Kick of meeting for the calibration group. The structure of the group, requirements and reporting needs are identified. First Task for the group is identified to be understanding the non-linear behavior observed for the small ePix10ka during the Dec calibration beamtime. The kick-off meeting slides and Philips results slides are attached below. The inital tasks and owners was identified as:


  • Run 2x quads + 2x epix10k_small with: (Kaz, Conny)
    • Charge injection with: Standard registers + DVDD,5sec,AVDD, standard length cables
    • Charge injection with:  Standard registers + (reversed power startup sequence)
    • Charge injection with: Standard registers + DVDD,5sec,AVDD, slightly lower voltage for one of the detectors
    • Charge injection with:  Standard registers + DVDD, 5sec,AVDD, longer cables
    • Dionisio’s HV pulser test (if available)? (Dionisio, Kaz, Conny)
    • Come to a conclusion whether we need to goto MFX and repeat.   PJB + Matt Hayes needed. 
  • Look at day1 vs day2 DG2 wave8 intensity difference (kaz)
  • Complete FH, FM, AML gain analysis (Kaz, Philip)
  • Xaviet + Scott learns psana/python data retrieval + learn how to set things up in lab.  (Xaviet, Scott, Philip, Bhavna)
  • Understand why DVDD + 5sec + AVDD is needed (Scott)
  • Register map + translation between ASC and TID.   (Scott + Philip)
